Conventional models of bargaining and reassurance under incomplete information assume that actors' behavioral signals are objectively cooperative or noncooperative. Even if actors are uncertain of each other's preferences, they know what types of actions the other will view as cooperative. Yet on many real-world issues, cooperation is subjective, and what constitutes a cooperative action is conditional on the receiver's preferences. We present a formal model showing that in these cases, two-sided incomplete information actually incentivizes honest behavior and facilitates credible signaling. Because uncertain senders do not know whether a particular action will be interpreted as cooperative, they have little incentive to misrepresent, and instead honestly pursue their true goals. Thus, where cooperation is subjective, mutual uncertainty is “offsetting,” such that credible signals allow actors to quickly and accurately update their beliefs. We illustrate this logic through a case study of the Sino–Soviet split, and highlight the model's implications for contemporary U.S.–China relations. 相似文献

There has been a long-standing discussion since the 1980s about the question whether new production models harbor a potential for extended employee participation and involvement, in most cases with disillusioning results. This paper is concerned with so called “agile methods”, which play an important part in the area of knowledge work in the course of the digital transformation. On the basis of two case studies from software development and industrial R&D, the paper examines the concrete implementation of these methods and the employees’ perspective upon them and their consequences. The result is that agile methods present a potential for extended employee participation and involvement; however, the realization of this potential depends on the concrete way how the agile concept of “empowerment” is implemented. 相似文献

The African people's relentless struggle to tell their own stories and take charge of their own historical languages is a prerequisite for achieving an African Renaissance. This argument, informed by Afrocentricity—a theoretical framework which advances the view that any examination of African issues must be informed by African history and culture—takes its cue from the great Senegalese Pan-Africanist and African Renaissance advocate, Cheikh Anta Diop. The year 2018 marks 70 years since Diop, at a tender age of 25, wrote his essay When will we be able to speak of an African Renaissance? On the occasion of the 70th anniversary of this article, it is appropriate that the African Renaissance project advocates take a moment and deeply reflect on how they can take African scholarship to higher levels and intensify and consolidate the struggle to liberate Africa from being preoccupied with the Eurocentric trajectory of privileging Europe and Europeans in all aspects of life—the intellectual, political, cultural, social and material. This article argues that embracing Africology—the Afrocentric approach to scholarship—is the first step towards the liberation of a scholarship project. Diop dedicated his life to using sciences—both the natural and social sciences for the liberation of Africa and humankind—to liberate Africans from inferiority complex, and Europeans from superiority complex. Although Diop recognised both the importance of science and ideology in the service of humanity, he drew a line between them. 相似文献
